[U-Boot] [PATCH V4 0/3] eMMC: support for Read Protected Memory Block (RPMB)

[Pierre Aubert]

This serie of patches adds some functions and a sub-command of 'mmc' for  programming the authentication key and for reading and writing the RPMB partition of an eMMC according to the JEDEC standard No. 64-A441

The sub-command rpmb is enabled by the flag CONFIG_SUPPORT_EMMC_RPMB defined
in the board configuration file.
It has been tested on a SabreSDP iMX6 board.

Changes in V4:
- use subcommand tables for 'mmc' command and 'mmc rpmb' subcommand.
- add 'mmc info' subcommand, which is the same as mmcinfo.
  mmcinfo is kept for compatibility.
- add changelog in commit comments.

Changes in V3:
- add entries in README for configuration options related to eMMC.
- new patch for adding the 'confirm_yesno' function as suggested by W.Denk
- improved test for existence of RPMB partition.
- fix of coding issues.

Changes in V2:
- use ALLOC_CACHE_ALIGN_BUFFER in rpmb.c instead of a static buffer for the 
  RPMB frames.
